Independent TV — channels unavailable

I ordered for it in march 2018 and got it installed in december 2018... It worked nicely for 1 month but then some channels were not coming especially hd one... Then cartoon channels stopped and now all sports channel are unavailable. The number given by company is just irritating. There are no replies of the mails which i did. This is the # service a company can provide.. I am shocked that it belongs to mr. Ambani
